Hey, I'm from Ask Mr. Robot. The trinket very likely WAS a downgrade, until today (sometimes robots are really smart). Ghostcrawler tweeted that the trinkets got a buff today. Once he posts the new proc info, we'll update our trinket estimates as well. So for now, hold out a bit longer and it's probably safe to assume the buffed Wushoolays is going to be better.

Also, check out the blog post Aliok linked - it's really helpful (but keep in mind, the commentary at the end is for the original 5.2 trinket values, not the new buffed values).

Digg, sorry I should have clarified. The trinket in game would have been a downgrade, until the patch today when they buffed it. We do not have the new proc information yet (ghostcrawler is probably posting that soon). Once we get that info, we'll update the site. Until then, it's probalby save to assume it will be better than the old trinkets now that they are buffed
